Synthetic trans-fat mentioned above is the one we really have to avoid. This type of fat, raises LDL (bad) cholesterol and at the same time, lower your HDL (good) cholesterol.

In a nutshell, we should not take too much butter, margarine or spreads as they all contain saturated fats and are high in calories.

- Butter : almost 60$ saturated fat, but no synthetic trans-fat. Butter usually has 52 grams of saturated fat per 100 grams- Margarine : usually has less than half the saturated fats of butter. In order to be labelled margarine, it must have a minimum percentage of unsaturated fats and a limited amount of saturated fat. The level of saturated fat may be as low as 11 grams per 100 grams or higher.- Spreads : Less overall fat (more water) and much less saturated fat than buter, straight margarine or cooking margarine.- Dairyspreads: combined butter and liquid vegetable oil, reducing saturated fat content but still higher than vegetable-based spreads. Dairy spreads have 19 to 35 grams of saturated fat per 100 grams- Cookingmargarines usually have 35 grams of saturated fat per 100 grams- Vegetableshortening (such as copha) may have as much as 98 grams of saturated fat per 100 grams.

So watch out the next time you go shop. Check the labels carefully. But if you still prefer ones that contain high saturated fats, limit the consumption and take it as a rare treat.
